Simplify square root of 3 times square root of 21

Answers

Step-by-step explanation: To multiply the square root of 3 times the square root of 21, we simply multiply the numbers that are inside the square roots together.

So, root 21 × root 3 equals root 63.

Next, we simplify the square root of 63. 63 factors as 3 x 21 and 21 factors as 3 x 7. So we have a pair of 3's which means a 3 can come out of the radical and the 7 doesn't pair up stays in the radical so our final answer is $\sqrt[3]{7}$ .

3√7 is the simplified value of the given expression.

To simplify the expression √3 * √21, we can combine the square roots and simplify under one radical if possible.

√3 * √21 = √(3 * 21)

Simplifying the product inside the radical:

√(3 * 21) = √63

Now, we can simplify further by factoring 63 into its prime factors:

√(3 * 21) = √(3 * 3 * 7)

Taking the square root of each factor:

√(3 * 3 * 7) = √3 * √3 * √7 = 3 * √7

Therefore, √3 * √21 simplifies to 3√7.

Write the given sentence as an equation. Tim s age in 7 years will be three times what it was 19 years ago.

Answers

Hi,
Let's say x if the actual age of Tim.
In 7 years, he will be old of x+7
19 years ago, his age was x-19
So
x+7=3*(x-19)
==>3x-57=x+7
==>3x-x=7+57
==>2x=64
x=64/2
==>x=32

Proof:
age=32
in 7 years: 32+7=39
19 years ago 32-19=11
and 39=3*11
